2021 Porsche 911 problems
The Porsche 911 (pronounced Nine Eleven or in German: Neunelf) is a two-door 2+2 high performance rear-engined sports car introduced in September 1964 by Porsche AG of Stuttgart, Germany. It has a rear-mounted flat-six engine and originally a torsion bar suspension. The car has been continuously enhanced through the years but the basic concept has remained unchanged. The engines were air-cooled until the introduction of the 996 series in 1998.
The 911 has been raced extensively by private and factory teams, in a variety of classes. It is among the most successful competition cars. In the mid-1970s, the naturally aspirated 911 Carrera RSR won world championship races including Targa Florio and the 24 Hours of Daytona. The 911-derived 935 turbo also won the 24 Hours of Le Mans in 1979. Porsche won the World Championship for Makes in 1976, 1977, 1978, and 1979 with 911-derived models.
In a 1999 poll to determine the Car of the Century, the 911 was fifth. It is one of two in the top five that had remained continuously in production (the original Beetle remained in production until 2003). The one millionth example was manufactured in May 2017 and is in the company's permanent collection.

The 911 C2 Carrera S is an amazing car that exceeded all my expectations. I find myself smiling or laughing while driving it because of how incredible and usable its performance is. It makes me feel like a better driver than I actually am. All the specifications are available online, so I won't mention them here. Instead, I'll discuss how those numbers translate into the real world. The car can easily achieve 0-60 and 60-0 without any drama. The brakes are so strong that I occasionally find myself checking the rearview mirror to make sure the car behind me has enough braking room. The 4-wheel steering is a must-have option. Lane changes at highway speeds and above are telepathic, with no body lean or upset to the chassis, just rock-solid performance. The interior is pleasant, but not luxurious considering the price. The sound levels are rather high at around town speeds, but they fade away on the highway. The storage is adequate, thanks to the small back seat, which can never be used for a human over 4 ft tall. I have noticed that when the temperature drops below 45 degrees, the tires have a hard time keeping contact during rapid acceleration from a standstill. This is typical of summer tires, but it makes me think that maybe I should have opted for the 4S. Update: The car now has 4K miles, and I still agree with my original review. I had the car on the track finally, and it was superb. Few stock vehicles can keep up with it. The steering feedback is excellent, and you can feel when you're approaching the limits of adhesion. The brakes are powerful, and I could late brake into a turn well after other vehicles were on their binders. It rained in the afternoon, which gave me the opportunity to test wet mode on the track. Once again, the car amazed me. All but 2 cars pitted during the storm, but my Porsche felt planted. You can't imagine the performance capability of this vehicle until you bring it to the track. 8K update: All the above still applies. The car has experienced many service bulletins, and engine mounts needed to be replaced on a recall.Not surprised as this was a very early build. Now for some negatives: Firstly, why is there no AM radio band? It seems ludicrous that a car of this cost couldn't include AM radio. Secondly, programming the garage door opener is a nightmare. Why can't they follow the software of other divisions like Volkswagen and Audi, which is easily programmed? Lastly, customer support from Porsche USA online or via telephone is pathetic, as is their vehicle owner's manual. Phone customer service representatives just repeat what's in the owner's manual, which is weak at best. Despite these negatives, I must say that the car is telepathic on the track, and throttle oversteer is easy to dial in. I'm still impressed by its capability, and if you purchase this vehicle and never track it, you'll be missing 80% of its capability. One negative track occurrence is with windows down as required at the track, wind turbulence and harmonic sound is unacceptable. I can't believe Porsche never ran this vehicle at 100 mph with the windows down. Small air deflectors placed by the outside mirrors are the answer. It's a shame that Porsche didn't realize this shortcoming. The fix cost me $120 plus installation. At the 15K update, the car is still reliable, but maintenance is EXPENSIVE. Rotors were $5k, and front tires weren't wearing well, but some camber and caster adjustments solved the problem. At the 20K update, it's more of the same great performance and owner satisfaction. PCA track instructors constantly marvel at the capability of a stock 991 S C2. There have been no service issues causing downtime as of yet. At 23K, all is good, and I'm sticking with all prior comments. I never mentioned that the car is easy to get in and out of, unlike other sports cars. The same goes for visibility, which is excellent, as opposed to my C8 Corvette.

This is a great car! It's fast, sporty, and will definitely turn heads. It's definitely worth the sacrifice.

I recently traded in my Corvette for the new 2020 Porsche Carrera S and I have never looked back. The performance and handling are a testament to true German engineering. While the straight line speed is similar, the Porsche's handling is tighter and the car just feels better built overall. The interior is incredibly comfortable and the instrument panel is fantastic. The only downside is that there is a bit of a learning curve when it comes to getting comfortable with all the controls. However, after a few weeks, I found that the controls came naturally to me. I was pleasantly surprised by all the capabilities of the controls, although I was disappointed to find that the radio did not have AM. Fortunately, I was able to connect my phone via Bluetooth and get the AM radio that way.

I've owned a 997 Carrera S and 991 GTS, but this machine surpasses them both. It's incredibly quick and comfortable, especially when you adjust the tire pressures to Porsche comfort levels. As my first 911 convertible, it's an absolute joy to drive - even at highway speeds with the top down and wind blocker. Everything is perfectly dialed in, from the PDK to the different driver modes, and the quality has a jewel-like precision. Every time I get behind the wheel, it's still an event.

You've got quite the collection! I noticed that you're missing the Cayenne, but I have to say, your 992 911 S is truly exceptional. It outshines even the GTS variants in terms of steering, handling, and acceleration. And let's be honest, it's not just good - it's perfect. The balance between insane capability and everyday comfort is truly remarkable. It's hard to imagine finding a better car than this.

After 40,000 miles and 5 years, the door inside panels need to be replaced due to the heat in Miami. This car has always been parked in the shade. The cost for replacement is $5200.00. There is a similar issue with the soft top, which will cost $8200.00.
